• Pump Servo
Rate control is achieved through speed changes to the solution pump. The pump servo setting is
programmed to control an electric motor used to actuate a hydraulic valve to adjust the hydraulic flow to the
solution pump.
• PWM Ground
Rate control is achieved through speed changes to the solution pump. The PWM Ground setting is
programmed to pulse the ground to an electric solenoid valve used to adjust the hydraulic flow to the
solution pump.
• Calibrated Reflow
Three-way boom valves are used to return product back to the tank in the off state. The returned flow is
calibrated with adjustment at each valve. Calibration is required any time the nozzles are changed.
• Ramsey Valve
A pneumatically-operated bypass valve. When air is supplied to the valve the rate increases; when air is
released from the valve the rate decreases.
